Our story
Since 1865, the International Telecommunication Union (ITU) has been at the centre of advances in communications – from telegraphy through to the modern world of satellites, mobile phones and the Internet.
The story of ITU is one of international cooperation, among governments, private companies, and other stakeholders. The continuing mission is to achieve the best practical solutions for integrating new technologies as they develop, and to spread their benefits to all.
ITU is for everyone. As ITU observes its 160th Anniversary in 2025, see some of the benefits you get through ITU’s work behind the scenes. Learn more.

ITU is for everyone
Every time you turn on your radio or television, hop on a plane, call home, access the Internet, find your location with your smartphone, tablet or personal computer, watch a weather forecast or view satellite images of the Earth, you use a vital service coordinated by the International Telecommunication Union (ITU) worldwide.
As ITU observes its 160th Anniversary in 2025, see some of the benefits you get through ITU’s work behind the scenes.
An internet backbone
Interconnected networks built to ITU standards facilitate communication, information sharing and access to knowledge and services. Today, an estimated 68% of people are Internet users. But disparities exist: an estimated 84% of people in high-income countries are covered by a 5G network, while only 4% of the population in low-income countries is. With partners, ITU develops standards, collects Internet use statistics, and promotes digital public infrastructure and digital literacy to connect the unconnected.
Mobile devices for development
Mobile phones, laptops, and other devices have changed how we purchase, study, socialize, and work. More than 95% of people over 10 years old own a mobile phone in high-income economies, compared to 56% in low-income economies. As mobile telephony rapidly expands, ITU is supporting developing countries in upgrading their networks, integrating new technologies, and expanding to unserved and underserved areas.
Satellite services
Earth’s orbital space is becoming more crowded. ITU manages radio spectrum used in space ensuring multimillion-dollar investments in satellite systems deliver connectivity and data worldwide. ITU ensures frequencies allocated to satellite systems are protected from harmful interference. ITU supports administrations as they coordinate satellite systems, and administer the Radio Regulations which contribute to sustainable and equitable access to space.
